ALONZO P. WVINSLOW, OF CLEVELAND, OHIO.

CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 283,057, dated October5, 1880.

Application filed March 11, 1880.

To all whom 2t may concern:

Be it known that I, ALoNzo P. WnvsLow, of Cleveland, in the county ofGuyahoga and State of Ohio, have invented a certain new and ImprovedRailway-Oar Roof; and I do hereby declare that the following is a full,clear, and complete description thereof.

The nature of my improvement relates to railway-car roofs; and itconsists in such construction of the same as to render them much lighterand cheaper than thosein ordinary use and equally strong and durable.

To attain this object sheets of tar-paper are arranged in connectionwith the roof structure, which is of peculiar arrangement, by which thecost and labor of a sheet-iron roof and its great weight are avoided.

The weight of the metal on a car-roof varies from three hundred to threehundred and fifty pounds, depending upon the size of the car and thethickness of the metal sheet. The weight of the sheeting which I use inplace of metal will be at least one hundred and twen tyfive per cent.less than that of iron and equally (if not more) durable. The greatadvantage of dispensing with this excess of weight is so obvious that itneeds no recital.

This improvement renders the cost of the roof at least two hundred totwo hundred and fifty per cent. less than when sheet metal is employed.

For a more detailed description of my improvement reference will be hadto the followin g specification, and to the annexed drawings, in which-Figure 1 is a sectional view of the roof; Fig. 2, a side view with aportion of the roof removed; Fig. 3, a side View. Figs. at and 5 are endviews with parts of the roof removed. Fig. 6 is a detached section.

Like letters of reference refer to like parts in the several views.

The general frame-work is shown in the drawings, in which A is theoutside roof or deck; B,'subrafters; C, stringers, as seen in' (Nomodel.)

Directly over the subroof D is laid sheeting of tar-paper in sectionsformed to lit the subroof and lap up on the sides of the subrafters B.The rafters are covered or capped over with tar-paper in sections shapedto the top, with the sides extending down the rafter, so as to lap overthe upturned ends of the adjoining tar-paper sections. Thisarrangementis shown in Figs. 2 and 6, in which G are the said papersections lying upon the subroof-boards D, the sides of which are turnedso as to lap up 011 the rafter B under the T-head a, as seen in Fig. 6.The connection or arrangement of the paper with the rafter B is the sameon both sides, as seen in the drawings, the channels or spaces H betweenthe rafters being covered with the tar-paper.

Over the'rafters B are placed tar-paper sections or caps I, the sides ofwhich are turned down, so as to come over the upturned sides of thesections G, as seen at d, Fig. 6. By this arrangement of the said papersection the entire roof of the car is covered over, which affords allthe protection to the interior of the car obtained by sheet metalwithout its excessive cost and weight.

For the purpose of securing the said paper sheets in place I use thestringers O, which are notched or halved out at the intersection withthe rafter B, by which the stringer is made to fit on the top and lapdown over the sides of the rafters with the paper sheeting interposedbetween the rafters and stringers, as seen in Fig. 2. The sheeting ofpaper is formed and made to lap over and down the ends of the roof, asseen at I, Fig. 4. By means of the stringers, in combination with therafters and framework, the sheeting is secured to the roof without nailsor pins.

The roof, constructed as described, is then. covered over with theordinary roofing-boards, as seen at A, to protect the sheeting andinterior parts of the roof.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In rooting for railway-cars, the combination of the subrafters, theinner deck or ceiling, the outer deck or roof-boards, and interposedcovering of tar-paper or felt, substantially as and for the purposedescribed.

2. In railway-ear roofing, with the subraftl or deck and ceiling,substantially as and for ers thereof and inner deck or ceiling, thetarthe purpose described. 10 paper or felt made to cover said raftersand In testimony whereof I affix my signature ceiling, the cap-piece,and outer deck or roof in presence of two Witnesses. 5 boards, allcombined substantially as and for ALONZO P. WINSLOW.
